Check the level of operational liquids on the car which is in horizontal position.

The recommended frequency: each 400 km of a run or weekly.

Operational liquids play an important role in operation of lubrication systems, coolings, braking, couplings and others. As these liquids gradually lose the properties, become soiled, evaporate and/or spent during operation of the car, their timely replacement and control of level is an integral part of maintenance.
